It might sound like the start of a trite joke, but it’s actually the entourage for one of the most highly anticipated papal trips in recent history.

As Pope Francis heads to Jordan, Bethlehem and Jerusalem this weekend, he’s bringing along two old friends from Argentina: Rabbi Abraham Skorka, who co-wrote a book with the Pope, and Sheikh Omar Abboud, who leads Argentina’s Muslim community.

The Vatican says it’s the first time that a pope’s official entourage has included interfaith leaders.

In a region roiled by competing religious and political visions, Francis’ chosen companions communicate an unmistakable message, church officials said.

“It’s highly symbolic, of course,” said the Rev. Thomas Rosica, a consultant to the Vatican press office.
